smaller eye and the coloration. The size of the eye expressed as a 

 fraction of the length of the head (to the hinder edge of the parietals) 

 is found to vary in L. capense from 0.11 to 0.19; in the type of L. 

 jacksoni the same ratio is 0.13 and the color pattern of this form is 

 also found in specimens with a much longer eye."

Mid-body scale rows, 25 to 29; ventrals, 187 to 213; subcaudals, 

 36 to 52. No. 41671 has a subcaudal subdivided so that there are 

 three scales in a row; the last ventral of this snake is also divided. 

 In No. 41696 three or four of the last ventrals show a tendency to 

 divide. The largest snake, partly skinned but head and tail complete 

 (No. 41671), measures 1395 (1240 + 155) mm., the smallest (No. 

 42002) 350 (310+40) m.m.

 third, fourth, and fifth entering the orbit on the right side of the head,
